Replace the manual tokenizer and recursive descent parser with a PEG
grammar using the pest library.
This migration involves introducing a formal grammar in formula.pest and
updating the parser implementation to utilize the generated Pest parser
with a tree-walking approach to construct the AST.
The change introduces a stricter requirement for identifiers: multi-word
identifiers must now be enclosed in pipe quotes (e.g., |Total Revenue|) and
are no longer accepted as bare words.
Tests have been updated to reflect the new parsing logic, remove
tokenizer-specific tests, and verify the new pipe-quoting and escape
semantics.
BREAKING CHANGE: Multi-word identifiers now require pipe-quoting (e.g. |Total Revenue|) and
are no longer accepted as bare words.

The records mode column filter excluded all categories starting with '_',
which hid _Measure. Changed to explicitly exclude only _Index and _Dim,
making _Measure visible as a data column. Updated the blank-model editing
test to reflect the new column order (_Measure first, Value last).

Simplify the commit_cell_value function by extracting its core logic into

Allow synthetic record edits to be applied directly to the model when not
in drill mode, whereas they remain staged in drill state when a drill
snapshot is active. This enables editing of records in plain records view.
Additionally, add validation to prevent creating records with empty
coordinates in both direct commits and when applying staged drill edits.
Includes regression tests for persistence in blank models, drill state
staging, and empty coordinate prevention.

Extract the formula AST and parser into a dedicated `improvise-formula`
crate and convert the project into a Cargo workspace.
The root crate now re-exports `improvise-formula` as `crate::formula` to
maintain backward compatibility for internal callers. The repository map is
updated to reflect the new crate structure.

Add helper methods to CmdContext to clarify layout state and synthetic

The render helper used in Grid tests previously did not recompute formulas,
meaning tests for computed values were either ignored or required manual
setup that didn't reflect actual application behavior.
Update the render helper to identify 'None' axis categories and trigger
recompute_formulas, and update all call sites to pass a mutable model.

When drilling into a cell that is the target of a formula, the resulting
record set was empty because the formula target coordinate itself does not
exist in the raw data.
This change strips the '_Measure' coordinate from the drill key if the
value is a known formula target, allowing the underlying data records that
feed the formula to be discovered.

Update the .improv file grammar to require version v2025-04-09 and remove

BREAKING CHANGE: The .improv grammar now strictly requires the version line 'v2025-04-09'.
Existing files without this line will fail to parse.

Update persistence logic for formulas and categories.
- Formulas targeting `_Measure` no longer include the category suffix in
Markdown.
- `_Measure` items are now excluded from the category section in Markdown
to avoid duplication with the formulas section.
- Improved Markdown parsing to correctly handle formulas without an
explicit category suffix, defaulting them to `_Measure` .
- Added logic to skip virtual index and dimension categories during
persistence.

Refactor command execution and buffer management.
- `CommitFormula` now defaults to targeting `_Measure` .
- `CommitFormula` no longer automatically clears the buffer; buffer
clearing is now handled by keymap sequences.
- Added `ClearBufferCmd` to the command registry.
- Updated `AddFormulaCmd` to support optional target category.
- Added `SetBuffer` effect to allow clearing buffers.

Implement keymap inheritance and sequence bindings.
- Added `parent` field to `Keymap` to support Emacs-style inheritance.
- Implemented `lookup` in `Keymap` to fall through to parent keymaps.
- Added `bind_seq` to allow multiple commands to be bound to a single key
pattern.
- Refactored existing keymaps to use sequences for common patterns like
Esc/Enter/Tab to clear buffers and change modes.

Refactor formula handling to use a virtual '_Measure' category.
- Formulas now default to targeting '_Measure' if no category is specified.
- '_Measure' items are dynamically computed from existing data items and
formula targets, preventing redundant item storage.
- Updated persistence to handle '_Measure' formulas and items correctly in
Markdown.
- Updated UI and model to use 'effective_item_names' for layout and item
resolution.
- Updated tests to reflect the new '_Measure' behavior.
